Pakistan has released nearly 340 Indian fishermen from prison despite recent tension caused by deadly violence along the disputed Kashmir border.

Pakistan and India regularly release fishermen who are detained after straying into each other's territorial waters.

Tensions between the two nuclear powered neighbors have increased recently after weeks of cross-border firing in Kashmir, with the two countries' military forces blaming each other for the unrest.

The Himalayan region has been in dispute since India and Pakistan gained independence from Britain in 1947, with both sides claiming it in full but controlling only part, and violence flares there from time to time.
